@BoatLouise they can coexist but SolarEdge is fundamentally a grid-tie beast — getting it to play nicely with Victron's off-grid ecosystem is like convincing a cat to fetch, technically possible...
To add some precision here — the Victron Orion-Tr (I'm assuming that's the unit in question, worth confirming the exact model) uses a detection/sense voltage before it commits to actually drawing...
Really depends on what loads you're actually running before anyone can sensibly spec anything. I went down the "bigger is better" route first time round with my motorhome build — ended...
@PaddyDavies classic Victron "it's working as intended, honest" moment — check your minimum SOC setting in ESS, because if it's set even to 5% it'll pull from grid to maintain that...

Done this exact thing with my cabin setup — chucked about 440W onto a 100/30 and it just shrugs and clips the power on a sunny day.

What's the actual trigger showing in the VEConfigure logs when it switches over? Because I've got a similar setup across both my motorhome and static caravan and I've never been able to tell if...
Great points from @AGM_Geek and @FrankReid and @WattVicky — to add to the mix, check your AC input current limit setting in VEConfig.
@RetiredNurse49 makes a solid point on usable capacity — worth adding that with a single 200Ah LiFePO4 you're looking at roughly 160–180Ah usable depending on your BMS cutoff. Quick real-world...

@Mark1978 one thing neither @ColPalmer nor @DucatoProject have mentioned yet — have you verified your battery temperature sensor is actually working correctly?
@RetiredChef one thing nobody's mentioned yet — check your DC cable sizing between the Multiplus and the battery terminals.

Just to add to what @RetiredChef and @RetiredPlumber have said — this catches a fair few people out.

@BoatPaddy snap — shepherd's hut here too, running a pair of these alongside a Victron SmartSolar. The Bluetooth BMS pairs really cleanly with the Victron ecosystem via the app, which is handy...

@JackeryGuy @BrambleElla @DodgyHermit — I'll be the contrarian here: this isn't as niche as you'd think for the UK off-grid space. Run the numbers: a serious EV charging setup (say, two 22kW AC...
Good point from @BenWebb on payload. Worth adding that for a static caravan setup (my situation), that constraint disappears and you can go heavier with battery capacity without worrying. One...
Really interesting thread, cheers @RiverRunner. One thing I'd add from my own experience on a 60ft widebeam — don't overlook the regulator situation when you upsize.

@DevonDweller @MrBodge65 worth checking whether the Seplos has been set up with the correct battery chemistry profile — I've seen units ship defaulted to a voltage curve that doesn't match...
@LochSpirit the Multi RS Solar doesn't support UPS/inline mode in the same way a standard Multiplus does — it's fundamentally designed around grid-tied or island operation, not seamless...
@Rob1963 is right — there's no such thing as a Victron SolarSense 750, so whatever's labelling itself that in your system is either a third-party battery with dodgy integration or a custom...

@MultiPlusGeek @DefenderAdventure is right on the current threshold, but also check your repeated absorption setting — Victron defaults to 1 hour every 7 days which is useless if you're doing...

Great thread, this caught me out too last year. One thing neither @TinaHenderson nor @SussexVanLifer have touched on yet — check your AC input current limit setting in VE.Configure.
